• the cylindrical roller 2 has the same configuration and performs the same operation as the roller device of the first embodiment.
• the frame 1 is composed of a bottom plate 1a and plate members 18 and 18a which are raised upward from both sides thereof. Further, a mounting plate lb is bent from the bottom plate 1a. Thereby, the mounting plate 1b is imparted with a property.
• a thermal head 22 is fixed on the portion 1 b.
• the support shaft 13 of the cylindrical roller 2 passes through the circular through hole 18b of the plate 18a, and is rotatably connected to the through hole 18b.
• the support shaft 14a of the cylindrical roller 2 penetrates the through hole 18c of the plate 18 and its flat portion 14b fits into the through hole 18c, so that the rotation is stopped. It is supported. Further, on the outer periphery of the flat portion 13a of the support shaft 13, a turning knob 19 made of fins is provided with a ⁇ (finally formed turning suppressing body 19a as shown in FIG.
• the outer periphery of the motion suppressor 19a is polygonal, specifically, an octagon, as shown in Fig. 6. Thus, the free end of 3 ⁇ 4; Is suppressed.
• the M-law of the free end of 3 ⁇ 4 / net 20 is fixed to the plate 18a with screws 20a.
• the planetary gear 8 revolves due to the rotation of the sun gear 7 as described with reference to FIGS. 3 and 4 in the first embodiment.
• the displacement between the first inner key wheel 10 and the second inner key wheel 11 occurs.
• the second Inner bell wheel 1 1 has a bearing body 1 2 with ⁇ 3 ⁇ 4! Since the rotation is stopped by the Fiber S rotation suppressing body 19a as in the above, the first inner bell wheel 10, that is, the cylindrical body 3 becomes the cylindrical body 4 and is decelerated and rotated.
• the belt-shaped print sheet 21 is thighed as shown by an arrow 300 as shown in FIG.
• the cylindrical roller 2 and the thermal head 22 are in pressure contact with each other because the mounting plate lb has elasticity as shown by 3 ⁇ 4. Therefore, the printing sheet 21 is conveyed by the rotation of the cylindrical roller 2.
• the printing sheet 21 is made of thermal paper
• information is recorded by energizing the thermal head 22.
• the rotational force is ⁇ Si ⁇ to the bearing body 12, the second inner wheel 11, the planetary gear 8 connected thereto, and the first inner wheel 10.
• the cylindrical roller 2 is rotated stepwise for each side of the polygon provided on the rotation suppressing body 19a.
• the print sheet 21 is manually fed in the direction of arrow 300 in FIG.
• the drive unit is provided in the cylindrical roller, and the drive unit is unitized with the frame on which the print head is mounted. Therefore, this roller device is compact and can be used as an information book by setting it to various types of electronic ⁇ .
• the elastic body on the bottom plate of the frame presses the thermal head against the cylindrical roller, so that the print sheet can be smoothly thighed.
• the structure is simplified because the ingot is also integrated with the frame.
• the rotation speed of the motor is controlled by the sun gear and the planetary gear.
• the cylindrical roller can be appropriately rotated.
• the present invention it is possible to prevent the planetary gear, the first and second internal gears from being damaged when manually rotating a cylindrical roller used in a printing machine or the like. Therefore, the printing sheet can be manually fed by manually rotating the cylindrical roller.
• an electronic device such as a pudding machine in which a mouth-to-mouth operation is actually performed.
• a printer having a compact configuration can be obtained.
